How to make Blender open on secondary monitor, including save/open/prefs window?
Try creating a new project, setting the all the windows as you want them to be and save it as your startup file.
This can be achieved by going to File &gt; Defaults &gt; Save Startup File.
I use this so Blender starts in both my monitors, but I see no reason why it woudn't work in your case. Hope it helps.
